Cool, let's get rolling! This hack chat is going to be more of a community discussion around Prize entries, unique ways of energy harvesting, and anything else about the Prize.
It's kind of a neat way to do power and communication. I've seen some groups that send data over the headphone jack as well.
OK, then can you tell us why was Power Harvesting chosen as one of the categories?
I spend a lot of my days running logistics for the prize and talking with individuals about how to get their entries to be epic. So I'm excited to answer any questions!
How are prize categories for the year created? Is there any community input on, say, 'categories for 2019'?
@Kris Winer Yes, the Power Harvesting Module Challenge was chosen because energy consumption is one of the biggest challenges facing humanity at the moment.
This is an area electrical engineers and makers can really use our skills to aid with
there should be a "ironic man" achievement for energy-saving achievements being sold for bitcoin :D
I think the vast majority of power harvesting entries might focus on solar energy and thermal electric generators. These have somewhat been exhausted in the DIY community, to some extent. I'm interested to see what new things people come up with. I think something that hasn't been quite tapped into is using people's sweat to make a battery and power some sort of wearable.
just my two cents anyways
We specifically chose modules because we wanted projects to focus on design pieces that can be used in a variety of applications moving forward. Hopefully these projects can be used in future projects that may have otherwise been powered with traditional means
@ðeshipu way too real
I'm looking forward to seeing some of the more innovative ideas; my project is just using an off-the-shelf IC to harvest power from a solar cell. The small sized form factor is unique but it isn't something anyone else couldn't do...
@Kris Winer if you don't mind sharing
What are you powering?
It's kind of hilarious that the new alternative currency (crypto) is actually directly adding to energy pollution rather han indirectly
"but it isn't something anyone else couldn't do" sounds like a good design
don't know if it helps with energy consumption. Millions of micropower devices need as much power as one air conditioner
the bitcoin proof-of-work algorithm is outdated, people should use more modern coins, like Waves with proof-of-stake
I have designed a bunch of different kinds of environmental sensors using either wifi, BLE or LoRa and combinations thereof. wifi is nearly impossible to power with a solar cell. BLE is the best match here. LoRa is so power efficient is doesn't really need power harvesting.
Plus where I am, I get ~6 hours of direct sun a day, so with a small solar cell that is ~40 mA per day, this is the power budget for any kind of remote sensor device arounf my house.
Unless you wanted to power LoRa with a pushbutton or piezoelectrics triggered by rain. Batteryless electronics is really interesting.
in most of EU you can use the rainwater with two electrodes as a battery :P
I am so excited about more unique and ingenious methods of power harvesting,. That is what I really want to see - ways of taking power from unlikely places and being used.
